Formula
Metres = feet × 0.3048. Centimetres = metres × 100. Inches = feet × 12. Optional planning centimetres = centimetres + allowance centimetres.

Allowance after exact conversion
These rows keep the measured feet conversion visible, then show how small centimetre allowances change the planning length for cutting, clearance, worksheets or quote notes.

Visual proof
Measured feet plus optional buffer
The printable report works as a height record, product dimension note, classroom conversion worksheet, cut-list reference or homeowner/tradie measurement record.
Visual grid
This result measures part of the space you live in
Length, area, volume and material estimates are grid problems too: measure the space, account for edges and allowances, then turn the pattern into a number you can use.

Inputs
- Feet
- 6 ft
- Optional allowance
- 0 cm
Method
Metres = feet × 0.3048. Centimetres = metres × 100. Inches = feet × 12. Optional planning centimetres = centimetres + allowance centimetres.
- For 6 ft, multiply 6 × 0.3048 = 1.8288 m. Convert to centimetres: 1.8288 × 100 = 182.88 cm. The same length is 6 × 12 = 72 inches.
Assumptions
- 1 international foot is exactly 0.3048 metres.
- 1 foot is exactly 12 inches, and 1 inch is exactly 2.54 centimetres.
- The optional allowance is added after the source feet value is converted, so measured length and planning adjustment stay separate.
- This is a unit conversion only. It does not decide building tolerance, product fit, cutting waste or compliance requirements.
Notes
Use this space on the printed report for client, supplier, classroom, job-location, measurement, quote or approval notes.
Worked example
For 6 ft, multiply 6 × 0.3048 = 1.8288 m. Convert to centimetres: 1.8288 × 100 = 182.88 cm. The same length is 6 × 12 = 72 inches.
Professional note
Master’s Tip: keep the original decimal-foot measurement beside the metre and centimetre result. If the number will be used for cutting, clearance or ordering, add that allowance as a separate line rather than hiding it inside a rounded conversion.
Regional and unit assumptions
Standard or basis: the international foot is exactly 0.3048 metres. This page uses transparent unit-conversion arithmetic based on exact international foot and inch definitions, with practical display rounding only after the exact conversion.
Assumptions and limitations

Questions
How many metres are in one foot?
One international foot is exactly 0.3048 metres.
What is the formula for feet to metres?
Multiply feet by 0.3048 to convert feet to metres.
How many metres is 6 feet?
6 feet is exactly 1.8288 metres, which is 182.88 centimetres.
Can I convert decimal feet such as 5.75 ft?
Yes. Decimal feet are accepted. For example, 5.75 ft means 5 feet and 9 inches because 0.75 × 12 = 9 inches.
Should I round before or after conversion?
Convert first using the exact factor, then round the displayed result to the precision needed for the record, drawing, quote or worksheet.
Calculation note
Feet-to-metres conversion is common when imperial measurements from height records, property notes, imported plans, sports data or workshop dimensions need to be used in a metric context. The conversion is exact at the unit-definition level, but the printed record still needs sensible rounding and clear source units.
The international foot has an exact metre value
Modern international-foot conversion uses the exact relationship 1 ft = 0.3048 m. That means a result such as 6 ft = 1.8288 m is not an approximation from this calculator; only the displayed rounding changes.
Decimal feet and tape-measure inches can both matter
A spreadsheet may store 5.75 ft, while a person with a tape measure may say 5 ft 9 in. Showing feet, inches, metres and centimetres together helps prevent a quiet unit mismatch in job notes, school work or product dimensions.
Allowances should not erase the measured value
Cutting tolerance, clearance or purchasing buffer belongs after the exact conversion. The printable report keeps the original feet value, metric result, formula and optional allowance visible so the calculation can be checked later.
